. TRANSPORTING-TRUCK.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed September 24, 1914. Serial N 0. 863,258.

To all whom it may concern:

Be it known that I, WILLIAM W. LEAOH, citizen of the United States ofAmerica, residing at Pineland, in the county of Sabine and State'ofTexas, have invented certain new and useful Improvements inTransporting-Trucks, of which the following is a specification.

This invention relates to certain new and useful improvements intransporting trucks for agricultural implements or the like, and whileshown and described in connection with the frame of a stump borer, itwillbe understood that itsuse is not confined thereto, but can beextended to all implements or machines of a transportable type.

The primary object of the invention is to provide a truck which can beoperated by one man and also to provide means which can be manipulatedso as to throw a transporting wheel into andout of engagement with theground so as to enable transporting of the machine when the wheel is onthe ground, and to enable the wheel to be moved out of engagement withthe ground to thereby allow the machine to solidly rest upon the groundafter transportation.

A further object of. the invention is to provide means for positivelylocking the wheel in ground engaging position and for also enabling thelocking means to be disengaged to thereby allow the frame to move downto engage the ground.

Further the invention aims to provide means whereby upon tilting of theframe to partially raise same from the ground, the transporting wheelwill be automatically locked in ground engaging position.

In the drawings: Figure 1 is a top plan view of the invention; Fig. 2 isa side elevation showing the wheel of the truck in contact with theearth, in full lines, for transporting purposes and the wheel forced toswing upward when released from the frameto the position shown in dottedlines when it encounters an obstruction in the earth; Fig. 3 is asection'on the line A-A ofFig. 2; and Fig. 4 is a detail perspectiveview of a portion, of the yoke.

The present illustration of the invention is shown in connection withthe frame of a stump boring machine which includes a pair of transverseinverted U-bars or uprights 1 and 2, secured to a pair of longitudinalbars 3 and 4 by means of clips 6, the bars 3 and 4 extending beyond theuprights 1 and 2 as clearly shown in the drawings. Brack ets 13 and 14are secured to the ends 7 and 8 of the bars 3 and 4, and are providedwith depending arms 15 and 16 respectively. Locking levers 17 and 18 arepivoted to the arms 15 and 16 respectively, at points intermediate theends of the bars 17 and 18.

The bars 3 and 4 have brackets 19 and 20 respectively secured thereto,the brackets having eyes or bearings 21 and 22 in which latter atransverse shaft 23 is journaled, the ends of the shaft being turned atright angles to provide cranks 24 and 25.

For the purpose of operating the pivoted locking levers 17 and 18 fromthe shaft 23 links 26 and 27 are pivotally connected to the upper endsof the levers 17 and 1S and to the cranks 24 and 25 respectively of theshaft 23, by which means, operation of the shaft 23 will be communicatedto both of the links 26 and 27 and thereby to the levers 17 and 18,simultaneously.

For the purpose of rocking or operating the shaft 23, an operating link28 is pivoted at one end to the crank 25 and at its opposite end to ahand operated lever 29 which latter is pivoted to the end portion 9 ofthe bar 4 and is tensionedby a coil spring 30, which latter acts tonormally hold the parts in their locked position shown in full lines inFig. 2. I

The transporting wheel 31 is mounted upon a yoke which consists of theside bars 32 and 33 which support the axle 34 at one of their ends andat their opposite ends are pivotally attached by the bolts 35 and 36 tothe end portions 7 and 8 of the bars 3 and 4. The yoke normally could bemoved upwardly and downwardly with respect to the ends 7 and 8 of thebars 3 and 4, but with use of the hereinabove described mechanism, themovement of the yoke is restricted or controlled by such mechanism. 7

In operation, it will be seen that the locking levers 17 and 18 arenormally held by. the spring with their lower ends in posltion to engagethe upper sides'of the yoke side bars and 33 when the frame is tilted upwardl y at its front, and when engaged with the yoke sides as shown infull lines on Fig. 2, the levers 17 and 18 prevent upward movement ofthe yoke and therewith the trans Jorting wheel 31 and thus allow thestructure to be transported; The spring 30 exerts. tension on the link28 and therethrough the shaft 23 and links 27 and 28 to vhold the levers17 and 18 in their justsired location and the operator desires to Iagain allow the machine to rest upon the legs of the frame, which legsare provided by the lower ends of the bars 1 and 2, the lever 29 ispulled rearwardly against the action of the spring 30 to the dotted lineposition shown in Fig. 2 thereby withdrawing the lower ends of thelocking levers 17 and 18 from engagement with the yoke sides 32 and 33into the dotted line position shown in Fig. 2, thereby releasing thewheel 31 and yoke and allowing them to pivotand be moved to the dottedline position shown in Fig. 2 upon encountering an obstruction in theearth thereby permitting the stump bor ing machine to be placed adjacentor in close proximity to the stump to be bored.

It will be noted that upon tilting of the frame. at its front, thelevers 17 and 18 are in the path of the yoke sides 32 and 33 and thelatter move the levers outwardly at and by engaging the lower endsthereof so that when the frame is lowered, the levers will engage theyoke sides and hold the frame bar 2 in the up position shown in fulllines in Fig. 2. The locking action is thus automatic, since by merelyraising the front end of the f 'ame from the ground, the levers l7 and18 act to automatically lock the carrier in position when the wheel ofsame is in ground engaging position.

What is claimed is: p

1. In combination with the frame of a transportable implement, a yokepivoted to the frame, a ground engaging wheel on the yoke, a rock shafton the frame, cranks on the rock shaft, links connected to the cranks,locking levers pivoted to the frame and engageable at their lower endswith the upper faces of the sides'of the yoke, said links being alsoconnected to the locking levers, a spring tensioned hand operating leverpivoted to the frame, and a link connected to the last named lever andto one of the cranks of the rock shaft.

2. In combination with the frame of a transportable implement, a wheelcarrier pivotally connected to the frame so as to be movable into andout of ground engaging positions, means comprisingswinging pawlsautomatically co-aoting with the carrier to lock the carrier to theframe when the wheel is in ground engaging position and a lever and linkmechanism toiopera-te the pawls.

3.
